Abstract
A platform with a signal generation unit and a transmitting unit. The signal generation unit is adapted to generate a spreading code sequence. The spreading code sequence has a reference chip with a rising edge and a falling edge. The signal generation unit is adapted to adjust the spreading code sequence to ensure that the rising edge or the falling edge of the reference chip arrives at a Virtual Timing Reference Station, VTRS, on a predetermined time (tref,VTRS). The transmitting unit is adapted to engage with the signal generation unit and adapted to transmit the spreading code sequence. Further, a user device for receiving the transmitted spreading code sequence.
Claims18
A platform comprising:
- a signal generation unit configured to generate a spreading code sequence, wherein the spreading code sequence has a reference chip with a rising edge and a falling edge, and wherein the signal generation unit is further configured to adjust the spreading code sequence to ensure that the rising edge or the falling edge of the reference chip arrives at a Virtual Timing Reference Station, VTRS, on a predetermined time (tref,VTRS);
- and
- a transmitting unit configured to engage with the signal generation unit and configured to transmit the spreading code sequence.
